It could just be the fuel injection tips have black tar build up. But, this sounds like the typical, 1980's problem with people who used to put cheap gas in their mercedes. You get gunk buildup in your gas pump. When the car is hot, the gunk expands and you get no gas flow. First try about 4 applications of puting a bottle of good fuel injection cleaning fluids in only half tank gas and let it run almost dry. If you don't see a substantial change, don't even waste your time playing with it trying to clean anything, those are only agrivating band aids on a broken leg. Change the fuel pump! your car should be as good as new.

Car sometimes stalls out when first run and when you shut it off and on it works fine then

Do you smell gas? if so it could be injectors that stay open. It could be a bad Check valve/fuel pressure regulator that lets the fuel drain back to the tank. that would explain the stall at first start up

My 1998 mercedes ml320 starts for 1or 2 seconds and then stalls.

You either have to replace the battery in your key fob or have it reprogrammed. Verify this by trying the second key, if you have it. AAA told me that you can reprogram it by leaving it in the ignition, with the key turned to the first position, overnight. I haven't tried it.

Do you have idle at 650 rpm per spec?
If you can adust idle to correct spec then you are right : it is an easy fix.
How do you do that: by adjusting the gas cable at engine side.
If this is not a fix, then things are not simple as it is. You don't have the right mixture of air/gas ratio: 14.6:1.
Try to addess it as early as possible so you can experience the least cost of solutions for remedy before preparing for the hight cost solution.
After all the solutions from your mechanic won't work, the last costly thing is your fuel distribution out of calibration. Good luck.

My mercedes Benz C 220 stalls when I come to a stop or in park .

Is the AC on? The compressor can take alot of power and make it lope. Engine mounts can make it shake. coils, cap, rotor and wires for tune up at a minimum. EZL if you can find one cheap. MAF also can cause issue. If it is a 1991-1995 check the engine wiring harness as they get brittle and degrade.
